Solution - Reducing fractions to their lowest terms

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "7.91" was replaced by "(791/100)".

Step  1  :

            791
 Simplify   ———
            100

Equation at the end of step  1  :

        791
  18 -  ———
        100

Step  2  :

Rewriting the whole as an Equivalent Fraction :

 2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  100  as the denominator :

           18     18 • 100
     18 =  ——  =  ————————
           1        100   

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

 2.2       Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 18 • 100 - (791)     1009
 ————————————————  =  ————
       100            100 

Final result :

  1009            
  ———— = 10.09000 
  100
